Description:
utility function to create a scannable from a given PV
Arguments:
name - user-specified name of a scannable to be created, e.g. pixium10_DataType
pv - EPICS identifier of pv to be used by the scannable, e.g. BL12I-EA-DET-10:CAM:DataType
addToNameSpace = if True, the scannable is accessible from the commandline after the call
getAsString - If True, output value is a string (useful for enum pv, in which case set getAsString=True, and set hasUnits=False)
hasUnits - If False, output value is not converted to units - useful for enum pv with getAsString=True
For example,
createScannableFromPV("pixium10_DataType", "BL12I-EA-DET-10:CAM:DataType", True, True, False)
creates a scannable for pv with the following enums:
caget -d 31 BL12I-EA-DET-10:CAM:DataType
BL12I-EA-DET-10:CAM:DataType
Native data type: DBF_ENUM
Request type: DBR_CTRL_ENUM
Element count: 1
Value: UInt32
Status: NO_ALARM
Severity: NO_ALARM

[ 1] UInt8
